Shipwrecks being brought back to life with ‘smart nanotech’

The American Chemical Society (ACS) is holding its 256th meeting from August 19 – 22, 2018 in Boston, Massachusetts, US. This August 21, 2018 news item on Nanowerk announces a ‘shipwreck’ presentation at the meeting,

Thousands of shipwrecks litter the seafloor all over the world, preserved in sediments and cold water. But when one of these ships is brought up from the depths, the wood quickly starts deteriorating. Today, scientists report a new way to use “smart” nanocomposites to conserve a 16th-century British warship, the Mary Rose, and its artifacts. The new approach could help preserve other salvaged ships by eliminating harmful acids without damaging the wooden structures themselves.

An August 21, 2018 ACS press release (also on EurekAlert), which originated the news item, delves further into the research and scientists’ after hours (?) activities,

“This project began over a glass of wine with Eleanor Schofield, Ph.D., who is head of conservation at the Mary Rose Trust,” recalls Serena Corr, Ph.D., the project’s principal investigator. “She was working on techniques to preserve the wood hull and assorted artifacts and needed a way to direct the treatment into the wood. We had been working with functional magnetic nanomaterials for applications in imaging, and we thought we might be able to apply this technology to the Mary Rose.”

The Mary Rose sank in 1545 off the south coast of England and remained under the seabed until she was salvaged in 1982, along with over 19,000 artifacts and pieces of timber. About 40 percent of the original structure survived. The ship and its artifacts give unique insights into Tudor seafaring and what it was like to live during that period. A state-of-the-art museum in Portsmouth, England, displays the ship’s hull and artifacts. A video about the ship and its artifacts can be viewed here.

While buried in the seabed, sulfur-reducing marine bacteria migrated into the wood of the Mary Rose and produced hydrogen sulfide. This gas reacted with iron ions from corroded fixtures like cannons to form iron sulfides. Although stable in low-oxygen environments, sulfur rapidly oxidizes in regular air in the presence of iron to form destructive acids. Corr’s goal was to avoid acid production by removing the free iron ions.

Once raised from the seabed, the ship was sprayed with cold water, which stopped it from drying out and prevented further microbial activity. The conservation team then sprayed the hull with different types of polyethylene glycol (PEG), a common polymer with a wide range of applications, to replace the water in the cellular structure of the wood and strengthen its outer layer.

Corr and her postdoctoral fellow Esther Rani Aluri, Ph.D., and Ph.D. candidate Enrique Sanchez at the University of Glasgow are devising a new family of tiny magnetic nanoparticles to aid in this process, in collaboration with Schofield and Rachel O’Reilly, Ph.D., at the University of Warwick. In their initial step, the team, led by Schofield, used synchrotron techniques to probe the nature of the sulfur species before turning the PEG sprays off, and then periodically as the ship dried. This was the first real-time experiment to closely examine  the evolution of oxidized sulfur and iron species. This accomplishment has informed efforts to design new targeted treatments for the removal of these harmful species from the Mary Rose wood.

The next step will be to use a nanocomposite based on core magnetic iron oxide nanoparticles that include agents on their surfaces that can remove the ions. The nanoparticles can be directly applied to the porous wood structure and guided to particular areas of the wood using external magnetic fields, a technique previously demonstrated for drug delivery. The nanocomposite will be encompassed in a heat-responsive polymer that protects the nanoparticles and provides a way to safely deliver them to and from the wood surface. A major advantage of this approach is that it allows for the complete removal of free iron and sulfate ions from the wood, and these nanocomposites can be tuned by tweaking their surfaces.

With this understanding, Corr notes, “Conservators will have, for the first time, a state-of-the-art quantitative and restorative method for the safe and rapid treatment of wooden artifacts. We plan to then transfer this technology to other materials recovered from the Mary Rose, such as textiles and leather.”

The researchers acknowledge funding from the Mary Rose Trust and the Leverhulme Trust.

There is a video about the Mary Rose produced by Agence France Presse (AFP) and published on Youtube in May 2013,

Here’s the text from AFP Mary Rose entry on Youtube,

The relics from the Mary Rose, the flagship of England’s navy when it sank in 1545 as a heartbroken king Henry VIII watched from the shore, have finally been reunited with the famous wreck in a new museum offering a view of life in Tudor times. Duration: 02:35

One more thing: Canadian shipwrecks

We don’t have a ‘Henry VIII’ story or ‘smart nano and shipwrecks’ story but we do have a federal agency devoted to underwater archaeology, Parks Canada Underwater Archaeology webpage,

Underwater archaeology deals with archaeological sites found below the surface of oceans, rivers, and lakes and on the foreshore. In addition to shipwrecks, underwater archaeologists study submerged aboriginal sites such as fish weirs and middens; remains of historic structures such as wharves, canal locks, and marine railways; sunken aircraft; and other submerged cultural heritage resources.

Underwater archaeology shares the same methodology and principles as archaeology carried out on land sites. All archaeology involves the careful study of artefacts, structures and features to reconstruct and explain the lives of people in the past. However, because it is carried out in a more challenging environment, underwater archaeological fieldwork is more complex than land archaeology.

Specialized techniques and equipment are required to work productively underwater. Staying warm during long dives is a constant concern, so underwater archaeologists often use masks that cover their entire faces, dry suits worn over layers of warm clothing, or in cases where the water is extremely cold, such as the excavation in Red Bay (Labrador), wet suits supplied with a flow of hot water. Underwater communication systems are used to talk to people on the surface or to other divers. Removing sediments covering underwater sites requires the controlled use of specially designed equipment such as suction airlifts and small dredges. Recording information underwater presents its own challenges. Special underwater paper is used for notes and drawings, while photo and video cameras are placed in waterproof housings.

Underwater archaeological fieldwork includes remote-sensing surveys using geophysical techniques, diving surveys to locate and map sites, site monitoring, and excavation. The success of an underwater archaeological project rests on accurate documentation of all aspects of the process. Meticulous mapping and recording are particularly essential when excavation is required, as artefacts and other physical evidence are permanently removed from their original contexts. Archaeologists aim to be able to reconstruct the entire site from the records they generate during fieldwork.

Podcast Transcript

Underwater Canada: Investigating Shipwrecks

Jessica Ouvrard: Welcome to “Discover Library and Archives Canada: Your History, Your Documentary Heritage.” I’m your host, Jessica Ouvrard. Join us as we showcase the treasures from our vaults; guide you through our many services; and introduce you to the people who acquire, safeguard and make known Canada’s documentary heritage.

Canada has a rich maritime history filled with many tragedies, from small boats [lost] in the Great Lakes, to the sinking of the Empress of Ireland in the St. Lawrence River, to Sir John Franklin’s doomed expeditions in the Arctic. The shipwrecks capture our imaginations and evoke images of tragedy, heroism, mystery and discovery. 2014 also marks the 100th anniversary of the sinking of the Empress of Ireland.

Marc-André Bernier, Chief of Parks Canada’s Underwater Archaeology Service, is joining us to discuss shipwrecks and their significance in Canada’s history, and LAC’s important role in the research, discovery and investigation of these shipwrecks.

Hello, Marc-André Bernier. Thank you for coming today.

Marc-André Bernier: My pleasure. Hello to you.

JO: For those who don’t know much about underwater archaeology, can you explain what it is and the risks and challenges that it presents?

MAB: I’ll start with the challenges rather than the risks, because there are obviously risks, but we try to minimize them. Diving is inherently risky. But I’ll start with the challenges because they are, to a certain extent, what characterize underwater archaeology.

We face a series of challenges that are more complicated, that make our work much more complicated than terrestrial archaeology. We work on water and underwater, and our working conditions are dictated by what happens outside, by nature. We can’t work every day on the water, especially if our work involves the sea or the ocean, for example. And when we work underwater, we have to deal with constraints in terms of time and sometimes visibility. That means that we have to be extremely well organized. Preparation is crucial. Logistics are crucial.

In terms of preparation, we need to properly prepare our research using archives and so on, but we also have to be prepared in terms of knowing what’s going on in the field. We need to know the environmental conditions and diving conditions, even when we can’t dive. Increasingly, the work involves heading into deeper areas that can only be reached by robots, by remotely operated equipment. So we have to be able to adapt.

We have to be very precise and very organized because sometimes we have only a few minutes to access a site that will tell us many historical secrets. So we have to come very well prepared.

And when we dive, we’re working in a foreign environment. We have to be good divers, yes, but we also have to have access to tools that will give us access to information. We have to take into account currents, darkness, and so on. The work is really very challenging. But with the rapid development of new technologies in recent years, we have access to more and more tools. We do basically the same work as archaeologists on land. However, the work is done in a completely different environment.

JO: A bit hostile in fact.

MAB: A bit hostile, but with sites, objects and information that are not accessible elsewhere. So there’s an opportunity to learn about history in a different way, and in some cases on a much larger scale.

JO: With all the maritime traffic in Canada, there must have been many accidents. Can you talk about them and give us an idea of the number?

MAB: People don’t realize that we’re a maritime country. We are a country that has evolved and developed around water. This was true even before the Europeans arrived. The First Nations often travelled by water. That travel increased or developed differently, if you will, when the Europeans arrived.

The St. Lawrence River, for example, and the Atlantic provinces were the point of entry and the route. We refer to different waterways, such as the Ottawa and Richelieu rivers. They constituted the route. So, there was heavy traffic, which meant many accidents. We’re talking about probably tens of thousands of shipwrecks if we include the Great Lakes and all the coasts of Canada. Since Canada has the longest coastline in the world, there is potential for shipwrecks. Only a small number of those shipwrecks have been found, but some are very significant and extremely impressive as well.

JO: Are there also many military ships, or is it more…?

MAB: That’s another thing that people don’t realize. There have been many military confrontations in Canadian waters, dating back to the New France era, or when Phips (Sir William Phips) arrived at Quebec City in 1690 and laid siege to the city. He arrived by ship and lost ships when he returned. During the Conquest, there were naval confrontations in Louisbourg, Nova Scotia; in Chaleur Bay; and even at Quebec City. Then, in the War of 1812, the Great Lakes were an extremely important maritime theatre of war in terms of naval battles. There are a number of examples in the Richelieu River.

Then we have the Second World War, with ships and German submarines. We all know the stories of the submarines that came inside the Gulf. So there are many military shipwrecks, from the New France era onward.

JO: What were the most significant shipwrecks in Canada? Have all the shipwrecks been found or…?

MAB: No. There are still shipwrecks that remain to be found. These days at Parks Canada, we’ve been looking for two of the shipwrecks that are considered among the most significant in the country: the HMS Erebus and the HMS Terror, Sir John Franklin’s ships lost in the Arctic. Franklin left England in 1845 to find the Northwest Passage, and he was never heard from again. Those are examples of significant shipwrecks that haven’t been found.

However, significance is always relative. A shipwreck may be very significant, especially if there is loss of life. It’s a tragic event that is deeply affecting. There are many shipwrecks that may not be seen as having national historic significance. However, at the local level, they are tragic stories that have very deep significance and that have profoundly affected an area.

That being said, there are ships that bear witness to memorable moments in the history of our country. Among the national historic sites of shipwrecks are, if we go back, the oldest shipwrecks: the Basque wrecks at Red Bay, Labrador, where whales were hunted in the 16th century. It’s even a UNESCO world heritage site. Then, from the New France era, there’s the Corossol from 1693 and the Phips wrecks from 1690. These are very significant shipwrecks.

Also of great significance are the Louisbourg shipwrecks, the battle site, the Battle of the Restigouche historic site, as well as shipwrecks such as the Hamilton and Scourge from the War of 1812. For all practical purposes, those shipwrecks are intact at the bottom of Lake Ontario. And the Franklin shipwrecks-even if they still haven’t been found-have been declared of national historic significance.

So there’s a wide range of shipwrecks that are significant, but there are thousands and thousands of shipwrecks that have significance. A shipwreck may also be of recreational significance. Some shipwrecks may be a little less historically significant, but for divers, they are exceptional sites for appreciating history and for having direct contact with history. That significance matters.

JO: Yes, they have a bit of a magical side.

MAB: They have a very magical side. When we dive shipwrecks, we travel through history. They give us direct access to our past.

JO: Yes. I imagine that finding a shipwreck is a bit like finding a needle in a haystack?

MAB: It can sometimes be a needle in a haystack, but often it’s by chance. Divers will sometimes stumble upon remains, and it leads to the discovery of a shipwreck. But usually, when we’re looking for a shipwreck, we have to start at the beginning and go to the source. We have to begin with the archives. We have to start by doing research, trying to find every small clue because searching in water over a large area is very difficult and complicated. We face logistical and environmental obstacles in our working conditions. It’s also expensive. We need to use ships and small boats.

There are different ways to find shipwrecks. At one extreme is a method that is technologically very simple. We dive and systematically search an area, if it’s not too deep. At the other extreme, we use the most sophisticated equipment. Today we have what we call robotic research vehicles. It is as sophisticated as launching the device, which is a bit like a self-guided torpedo. We launch it and recover it a few hours later. It carries out a sonar sweep of the bottom along a pre-programmed path. Between the two, we have a range of methods.

Basically, we have to properly define the boundaries of the area. It’s detective work. We have to try to recreate the events and define our search area, then use the proper equipment. The side-scan sonar gives us an image, and magnetometers detect metal. We have to decide which of the tools we’ll use. If we don’t do the research beforehand, we’ll lose a great deal of time.

JO: Have you used the LAC collections in your research, and what types of documents have you found?

MAB: Yes, as often as possible. We try to use the off-site archives, but it’s important to have access to the sources. Our research always starts with the archives. As for the types of documents, I mentioned the Basque documents that were collected through Library and Archives Canada. I’ve personally used colonial archives a lot. For the Corossol sinking in 1693, I remember looking at documents and correspondence that talked about the French recovery from the shipwreck the year after 1693, and the entire Phips epic.

At LAC, there’s a copy of the paintings of Creswell [Samuel Gurney Cresswell], who was an illustrator, painter, and also a lieutenant, in charge of doing illustrations during the HMS Investigator’s journey through the Arctic. So there’s a wide variety of documents, and sometimes we are surprised by the personal correspondence, which gives us details that official documents can’t provide.

JO: How do these documents help you in your research?

MAB: The archival records are always surprising. They help us in every respect. You have to see archaeology as detective work. Every detail is significant. It can be the change in topographical names on old maps that refer to events. There are many “Wreck Points” or “Pointe à la barque,” “Anse à la barque,” and so on. They refer to events. People named places after events. So we can always be surprised by bits of information that seem trivial at first.

It ranges from information on the sites and on the events that led to a shipwreck, to what happened after the sinking and what happened overall. What we want is not only to understand an event, but also to understand the event in the larger context of history, such as the history of navigation. Sometimes, the records provide that broader information.

It ranges from the research information to the analysis afterward: what we have, what we found, what it means and what it says about our history. That’s where the records offer limitless possibilities. We always have surprises. That’s why we enjoy coming to the archives, because we never know what we’ll discover.

JO: Yes, it’s always great to open a box.

MAB: It’s like Christmas. It’s like Christmas when we start delving into archival records, and it’s a sort of prelude to what happens in archaeology. When we reach a site, we’re always excited by what the site has to offer. But we have to be prepared to understand it. That’s why preparation using archives is extremely important to our work.

JO: In terms of LAC sources, do you often look at historical maps? Do you look at the different ones, because we have quite a large collection…

MAB: Quite exceptional, yes.

JO: … from the beginning until now?

MAB: Yes. They provide a lot of information, and we use them, like all sources, as much as possible. We look for different things on the maps. Obviously, we look for places that may show shipwreck locations. These maps may also show the navigation corridors or charts. The old charts show anchorages and routes. They help us recreate navigation habits, which helps us understand the navigation and maritime mindset of the era and gives us clues as to where the ships went and where they were lost.

These maps give us that type of information. They also give us information on the topography and the names of places that have changed over the years. Take the example of the Corossol in the Sept-Îles bay. One of the islands in that bay is called Corossol. For years, people looked for the French ship, the Corossol, near that island. However, Manowin Island was also called Corossol at that time and its name changed. So in the old maps, we traced the origin, and the ship lies much closer to that island. Those are some of the clues.

We also have magnificent maps. One in particular comes to mind. It was created in the 19th century on the Îles-de-la-Madeleine by an insurance company agent who made a wreck map of all the shipwrecks that he knew of. To us, that’s like candy. It’s one of the opportunities that maps provide. Maps are magnificent even if we don’t find clues. Just to admire them-they’re absolutely magnificent.

JO: From a historical point of view, why is it important to study shipwrecks?

MAB: Shipwrecks are in fact a microcosm. They represent a small world. During the time of the voyage, there was a world of its own inside the ship. That in itself is interesting. How did people live on board? What were they carrying? These are clues. The advantage of a shipwreck is that it’s like a Polaroid, a fixed image of a specific point in time. When we study a city such as Quebec City that has been continuously occupied, sometimes it’s difficult to see the separation between eras, or even between events. A shipwreck shows a specific time and specific place.

JO: And it’s frozen in time.

MAB: And it’s frozen in time. So here’s an image, in 1740, what did we have? Of course, we find objects made in other eras that were still in use in that time period. But it really gives us a fixed image, a capsule. We often have an image of a time capsule. It’s very useful, because it’s very rare to have these mini Pompeiis, and we have them underwater. It’s absolutely fascinating and interesting. It’s one of the contributions of underwater archaeology.

The other thing is that we don’t necessarily find the same type of material underwater as on land. The preservation conditions are completely different. On land, we find a great deal of metal. Iron stays fairly well preserved. But there’s not much organic material, unless the environment is extremely humid or extremely dry. Underwater, organic materials are very well preserved, especially if the sedimentation is fairly quick. I remember finding cartouches from 1690 that still had paper around them. So the preservation conditions are absolutely exceptional.

That’s why it’s important. The shipwrecks give us unique information that complements what we find on land, but they also offer something that can’t be found elsewhere.

JO: I imagine that there are preservation problems once it’s…

MAB: And that’s the other challenge.

JO: Yes, certainly.

MAB: If an object is brought up, we have to be ready to take action because it starts to degrade the moment we move it…

JO: It comes into contact with oxygen.

MAB: … Yes, but even when we move it, we expose it to a new corrosion, a new degradation. If we bring it to the surface right away, the process accelerates very quickly. We have to keep the object damp. We always have to be ready to take action. For example, if the water heats up too fast, micro-organisms may develop that accelerate the degradation. We then have to be ready to start preservation treatments, which can take years depending on the object. It’s an enormous responsibility and we have to be ready to handle it, if not, we destroy…

JO: … the heritage.

MAB: … what we are trying to save, and that’s to everyone’s detriment.

JO: Why do you think that people are so fascinated by archaeology, and more specifically by shipwrecks?

MAB: That’s also a paradox. We say that people aren’t interested in history. I am firmly convinced that people enjoy history and are interested in it. It must be well narrated, but people are interested in history. There’s already an interest in our past and in our links with the past. If people feel directly affected by the past, they’ll be fascinated by it. If we add on top of that the element of discovery, and archaeology is discovery, and all the myths surrounding artefact hunters…

JO: … treasure hunters.

MAB: … treasures, and so on. It’s an image that people have. Yes, we hunt treasure, but historical treasure. That image applies even more strongly to shipwrecks. There’s always that myth of the Spanish galleon filled with gold. Everyone thinks that all shipwrecks contain a treasure. That being said, there’s a fascination with discovery and with the past, and add on top of that the notion of the bottom of the sea: it’s the final frontier, where we can be surprised by what we discover. Since these discoveries are often remarkably well preserved, people are absolutely fascinated.

We grow up with stories of pirates, shipwrecks and lost ships. These are powerful images. A shipwreck is an image that captures the imagination. But a shipwreck, when we dive a shipwreck, we have direct contact with the past. People are fascinated by that.

JO: Are shipwreck sites accessible to divers?

MAB: Shipwreck sites are very accessible to divers. For us, it’s a basic principle. We want people to be able to visit these sites. Very rarely do we limit access to a site. We do, for example, in Louisbourg, Nova Scotia. The site is accessible, but with a guide. The site must be visited with a guide because the wrecks are unique and very fragile.

However, the basic principle is that, as I was saying, we should try to allow people to savour and absorb the spirit of the site. The best way is to visit the site. So there are sites that are accessible, and we try to make them accessible. We not only make them accessible, but we also promote them. We’re developing tools to provide information to people.

It’s also important to raise awareness. We have the opportunity and privilege to visit the sites. We have to ensure that our children and grandchildren have the same opportunity. So we have to protect and respect [the sites]. In that spirit, the sites have to be accessible because these experiences are absolutely incredible. With technology, we can now make them accessible not only to divers but also virtually, which is interesting and stimulating. Nowadays there are opportunities to make all these wonders available to as many people as possible, even if they don’t have the chance to dive.

JO: How long has Parks Canada been involved in underwater archaeology?

MAB: 2014 marks the 50th anniversary of the first dives at Fort Lennox in 1964 by Sean Gilmore and Walter Zacharchuk. That’s where it began. We’re going back there in August of this year, to the birthplace of underwater archaeology at Parks Canada.

We’re one of the oldest teams in the world, if we can say that. The first time an archaeologist dived a site was in 1960, so we were there basically at the beginning. Parks Canada joined the adventure very early on and it continues to be a part of it to this day. I believe that we’ve studied 225 sites across Canada, in the three oceans, the Great Lakes, rivers, truly across the entire country. We have a wealth of experience, and we’ll celebrate that this year by returning to Fort Lennox where it all began.

JO: Congratulations!

MAB: Thank you very much.

JO: 2014 marks the 100th anniversary of the sinking of the Empress of Ireland. What can you tell us about this maritime accident?

MAB: The story of the Empress begins on May 28, 1914. The Empress of Ireland left Quebec City for England with first, second and third class passengers on board. The Empress left Quebec in the late afternoon, with more than 1,400 passengers and crew on board. The ship headed down the St. Lawrence to Pointe au Père, a pilot station, because pilots were needed to navigate the St. Lawrence, given the reefs and hazards.

The pilot left the Empress at the Pointe au Père pilot station, and the ship resumed her journey. At the same time, the Storstad, a cargo ship, was heading in the opposite direction. In the fog, the two ships collided. The Storstad rammed the Empress of Ireland, creating a hole that immediately filled with water.

At that moment, it was after 1:30 a.m., so almost 2:00 a.m. It was night and foggy. The ship sank within 14 minutes, with a loss of 1,012 lives. Over 400 people survived, but over 1,000 people [died]. Many survivors were pulled from the water either by the ship that collided with the Empress or by other ships that were immediately dispatched.

JO: 14 minutes…

MAB: … In 14 minutes, the ship sank. The water rushed in and the ship sank extremely fast, leaving very little opportunity for people, especially those deeper inside the ship, to save themselves.

JO: So a disaster.

MAB: The greatest maritime tragedy in the history of the country.

JO: What’s your most unforgettable experience at an underwater archaeology site?

MAB :I’ve been doing this job for 24 years now, and I can tell you that I have had extraordinary experiences! There are two that stand out.

One was a Second World War plane in Longue-Pointe-de-Mingan that sank after takeoff. Five of the nine crew members drowned in the plane. In 2009, the plane was found intact at a depth of 40 metres. We knew that five of the crew members were still inside. What was absolutely fascinating, apart from the sense of contact and the very touching story, was that we had the opportunity, chance and privilege to have people who were on the beach when the event occurred, who saw the accident and who saw the soldiers board right beforehand. They told us how it happened and they are a direct link. They are part of the history and they experienced that history.

That was an absolutely incredible human experience. We worked with the American forces to recover the remains of the soldiers. Seeing people who had witnessed the event and who could participate 70 years later was a very powerful moment. Diving the wreck of that plane was truly a journey through time.

The other experience was with the HMS Investigator in the Arctic. That’s the ship that was credited with discovering the Northwest Passage. Actually, the crew found it, since the ship remained trapped in the ice and the crew continued on foot and were saved by another ship. The ship is practically intact up to the upper deck in ten metres of water. When you go down there, the area is completely isolated. The crew spent two winters there. On land we can see the remains of the equipment that they left on the ground. Three graves are also visible. So we can absorb the fact that they were in this environment, which was completely hostile, for two years, with the hope of being rescued.

And the ship: we then dive this amazing exploration machine that’s still upright, with its iron-clad prow to break the ice. It’s an icebreaker from the 1850s. We dive on the deck, with the debris left by the ice, the pieces of the ship completely sheared off by the ice. But underneath that is a complete ship, and on the inside, everything that the people left on board.

I often say that it’s like a time travel machine. We are transported and we can absorb the spirit of the site. That’s what I believe is important, and what we at Parks [Canada] try to impart, the spirit of the site. There was a historic moment, but it occurred at a site. That site must be seen and experienced for maximum appreciation. That’s part of the essence of the historic event and the site. On that site, we truly felt it.

JO: Thank you very much for coming to speak with us today. We greatly appreciate your knowledge of underwater Canada. Thank you.

MAB: Thank you very much.

JO: To learn more about shipwrecks, visit our website Shipwreck Investigations at lac-bac.gc.ca/sos/shipwrecks or read our articles on shipwrecks on thediscoverblog.com [I found other subjects but not shipwrecks in my admittedly brief search of the blog].

Thank you for joining us. I’m your host, Jessica Ouvrard, and you’ve been listening to “Discover Library and Archives Canada-where Canadian history, literature and culture await you.” A special thanks to our guest today, Marc-André Bernier.

A couple of comments. (1) It seems that neither Mr. Bernier nor his team have ever dived on the West Coast or west of Ottawa for that matter. (2) Given Bernier’s comments about oxygen and the degradation of artefacts once exposed to the air, I imagine there’s a fair of amount of excitement and interest in Corr’s work on ‘smart nanotech’ for shipwrecks.

Nova Scotia’s (Canada) Sona Nanotech and its gold nanoparticles move

I hope one day to have at least one piece on nanotechnology for each province, the Yukon, and the territories. Unfortunately, today (Nov. 2, 2016) will not be the day I add one previously unsung province, etc. to the list as Nova Scotia has previously graced this blog with a nanotechnology story (my June 5, 2016 posting).

The latest nano news from Nova Scotia is found in a Nov. 1, 2016 article by James Risdon for the Chronicle Herald,

A Nova Scotia biotech startup with big plans for its super-small, non-toxic gold particles is looking to move its lab facilities to Halifax and expand.

Andrew McLeod, Sona Nanotech Ltd.’s president and chief operating officer, said Tuesday the company is already looking for lab space in Halifax and wants to hire three additional employees to handle production, research and business development.

Sona Nanotech has two products, its Gemini and Omni gold particles, intended to be used in the health-care industry for such things as the treatment of cancer and diagnostic testing.

These particles are measured in nanometres.

“You’re talking about something that’s on the order of millionths of the width of a human hair,” said McLeod. [The comparison measurements I’ve seen most frequestion for a single nanometre is 1/50,000 or 1/60,000 or 1/100,000 of a hair.]

While other players make gold particles, Sona Nanotech has developed a way to make its products so that they are free of a toxic chemical ,and that’s opening doors for the Nova Scotia startup whose products can be used inside the human body.

There’s already talk of Sona Nanotech teaming up with an as-yet-unnamed Canadian organization for a cancer research project, but McLeod was tight-lipped about the details.

Congratulations to Sona Nano!

For anyone curious about the business aspects of the story, I recommend reading Risdon’s article in its entirety.

Sona Nanotech’s website can be found here,

Sona Nanotech Ltd. has leveraged its team’s unique knowledge and experience with novel surface chemistry methods and surfactants to create a disruptive leap forward in metallic nanoparticle technology.

Co-founders Dr. Gerrard Marangoni, Dr. Kulbir Singh, and Dr. Michael McAlduff recognized the role that gold nanoparticles can play in a variety of life sciences applications, e.g.,  in-vivo 3-D imaging, GNR-enabled diagnostic test products and other cutting edge medical applications.  Gold nanorods can be enabling technologies for non-invasive targeted cell, tumor, tissue and organ treatments such as photothermal cancer cell destruction, and location specific drug and pain treatment.

The Problem
Gold nanorods have been made to date with toxic CTAB [cationic surfactant cethyltrimetylammonium bromide] which makes them much less attractive for in-vivo medical applications.

The Solution
100% CTAB-FREE – Gemini™ and Omni™ Patent-Pending Gold Nanorods – from Sona Nanotech Ltd.

The Problem
For a given colour contrast, large gold nanospheres are not as stable or mobile as gold nanorods (dip tests).

The Solution
Stable, high loading capacity GNRs [gold nanorods] from Sona Nanotech offer a broad range of rich, high contrast test color options.

So, there you have it.

Coordinator
Varun Bhatta, Manipal Centre for Philosophy and Humanities

Description:
Applications from post-graduate and doctoral students in the fields of philosophy, philosophy of science and social sciences, history and philosophy of science, science and technology studies, and cognate fields are invited to a five-day summer school in India, made possible by collaborations between institutions and scholars in Canada, India and Southeast Asia. This will be an excellent opportunity for graduate students interested in receiving advanced training in the philosophy of science and science and technology studies, with a focus on scientific objects and their relation to cosmopolitanism.

The paradigm of scientific objects has undergone a major transformation in recent times. Today, scientific objects are not limited to microscopic or major astronomical objects. A new category of objects involves ontological modes of data, grids, simulation, visualization, etc. Such modes of objects are not merely peripheral props or outcomes of scientific endeavour. They actively constitute scientific theorizing, experimentation and instrumentation, and catalyze notions of cosmopolitanism in the digital world. Cosmopolitanism in this context is defined as a model of cultural and political engagement based on multidirectional exchange and contact across borders. A cosmopolitan approach treats science as a contingent, multifaceted and multicultural network of exchange. The summer school will engage with philosophical themes around the nature of new scientific objects and digital cosmopolitanism.

“The event is organized by the Manipal Centre for Philosophy and Humanities (Manipal University) and by the Social Sciences and Humanities Research Council of Canada-funded Cosmopolitanism and the Local in Science and Nature, a three-year project to establish a research network on cosmopolitanism in science with partners in Canada, India, and Southeast Asia. The project closely examines the actual types of negotiations that go into the making of science and its culture within an increasingly globalized landscape.

Program and Faculty:
Each of the days will be split among:
(a) Background sessions led by Arun Bala, Gordon McOuat and Sundar Sarukkai,
(b) Sessions led by other faculty members with recognized expertise in the theme, and
(c) Sessions devoted to student research projects.

There will be plenty of opportunities for interaction and participation. The seminar will be held in English and readings will be circulated in advance. Special events will be organized to complement session content. There also will be opportunities for exploring the incredible richness and diversity of the region.

Selection Criteria:
We seek outstanding graduate students from Canada, India and Southeast Asia. We will prioritize applications from graduate students in disciplines or with experience in philosophy, philosophy of science, social studies, the history and philosophy of science, or science and technology studies.

Location and Accommodations:
The event will be hosted by the Manipal Centre for Philosophy and Humanities in the picturesque ocean-side state of Karnataka in south-western India. Students will be housed in student residences. The space is wheelchair accessible.

Fees:
A registration fee of Rs 1500 for Indian students and $100 CAD for international students will be charged. This fee will include accommodations and some meals.

Financial Coverage:

Students from India:
Travel for India-based students will be covered by the summer school sponsors.

Students from Canada and Southeast Asia:
Pending government funding, travel costs may be defrayed for students from Canada or Southeast Asia. Students should indicate in their applications whether they have access to travel support (confirmed or unconfirmed) from home institutions or funding agencies. This will not affect the selection process. Acceptance letters will include more information on travel support.

Students from outside Canada, India and Southeast Asia:
Students from outside Canada, India and Southeast Asia will be expected to provide their own funding.

Students at home institutions of “Cosmopolitanism and the Local in Science and Nature” team members are strongly encouraged to contact the local team member to discuss funding options. Information on the project’s partners and team members is available on the project’s “About Us” page: www.CosmoLocal.org/about-us.

Any travel support will be considered as co-sponsorship to this international training event and acknowledged accordingly. Further information on funding will be included with acceptance letters.

The last bit of information for this post concerns the Situating Science research cluster mentioned here many times. Situating Science was a seven-year project funded by the Social Sciences and Humanities Research Council (SSHRC) which has become the Canadian Consortium for Situating Science and Technology (CCSST) and has some sort of a relationship (some of the Situating Science organizers have moved over) to the Cosmopolitanism project. The consortium seems to be a somewhat diminished version of the cluster so you may want to check it out now while some of the information is still current.

News of this partnership is exciting especially in light of the objectives as described on the Cosmopolitanism & the Local in Science & Nature website’s About Us page,

Specifically, the project will:

  1. Expose a hitherto largely Eurocentric scholarly community in Canada to widening international perspectives and methods, [emphasis mine]
  2. Build on past successes at border-crossings and exchanges between the participants,
  3. Facilitate a much needed nation-wide organization and exchange amongst Indian and South East Asian scholars, in concert with their Canadian counterparts, by integrating into an international network,
  4. Open up new perspectives on the genesis and place of globalized science, and thereby
  5. Offer alternative ways to conceptualize and engage globalization itself, and especially the globalization of knowledge and science.
  6. Bring the managerial team together for joint discussion, research exchange, leveraging and planning – all in the aid of laying the grounds of a sustainable partnership

I’m not sure ‘expose’ is the verb I’d use here since it’s perfectly obvious that the Canadian scholarly community is eurocentric. For confirmation all you have to do is look at the expert panels convened by the Council of Canadian Academies for their various assessments (e.g. The Expert Panel on the State of Canada’s Science Culture). Instead of ‘expose’, I’d use ‘Shift conscious and unconscious assumptions within a largely eurocentric Canadian scholarly community to widening perspectives’.

As for Situating Science, there is this (from its About Us page; Note: Links have been removed),

Created in 2007 with the generous funding of the Social Sciences and Humanities Research Council of Canada Strategic Knowledge Cluster grant, Situating Science is a seven-year project promoting communication and collaboration among humanists and social scientists that are engaged in the study of science and technology.

At the end of our 7 years, we can boast a number of collaborative successes. We helped organize and support over 20 conferences and workshops, 4 national lecture series, 6 summer schools, and dozens of other events. Our network helped facilitate the development of 4 new programs of study at partner institutions. We leveraged more than one million dollars from Nodal partner universities plus more than one million dollars from over 200 supporting and partnering organizations. We hired over 30 students and 9 postdoctoral fellows. The events resulted in over 60 videos and podcasts as well as dozens of student blogs and over 50 publications.

I see the Situating Science project is coming to an end and I’m sorry to see it go. I think I will write more about Situating Science in one of my end-of-year posts. Getting back to the postdoc position, good luck to all the applicants!

2014 Canadian Science Policy Conference extends early bird registration until Sept. 30, 2014

If you register before Oct. 1, 2014 (tomorrow), you will be eligible to receive an ‘early bird’ discount for the 6th annual (2014) Canadian Science Policy Conference being held in Halifax, Nova Scotia from Oct. 15 – 17, 2014.

The revolving/looping banner on the conference website, on Monday, Sept. 29, 2014 featured an all male, all white set of speakers intended to lure participants. An unusual choice in this day and age. In any event, the revolving banner seems to have disappeared.

The agenda for the 2014 conference was previously included in a Sept. 3, 2014 posting about it and a super-saver registrationdiscount available to Sept. 9. As I noted at the time, the organizers needed at least one or two names that would attract registrants and I imagine that having the federal Canadian government Minister of State responsible for Science and Technology, Ed Holder, and, the province of Nova Scotia’s Minister of Economic and Rural Development and Tourism, Minister of Acadian Affairs and the Minister responsible for Nova Scotia Business Inc., and the Innovation Corporation Act – Cape Breton-Richmond, Michael P. Samson, have helped to fill that bill.

The two co-chairs for the 2014 version of this Canadian Science Policy Conference reflect the increasing concern about science, economics, and monetary advancement. Frank McKenna, a former premier of the province of New Brunswick, and a former Canadian ambassador to Washington, DC, is currently, according to his Wikipedia entry,

… Deputy Chair, TD Bank Financial Group effective May 1, 2006.[8] McKenna is responsible for helping to build long-term business relationships that support TD’s growth strategy in Canada and the United States.

McKenna is responsible for supporting the company in its customer acquisition strategy, particularly in the areas of wholesale and commercial banking. In addition, he is responsible for representing TD as it works to expand its North American presence as one of the continent’s ten largest banks, as measured by market capitalization.

As for John Risley, there’s this from a Dec. 19, 2013 article by Stephen Kimber for Canadian publication, Atlantic Business,

Billionaire seafood baron insists that business, not government, must lead Atlantic Canada out of its economic malaise

“The problem with doing profiles…” John Risley begins, and I realize I’ve already lost control of this particular interview before I even ask my first question. “I mean, look,” he continues, kindly enough, “this is your editorial licence, not mine.”

It had all seemed simple enough back in July 2013 during an editorial meeting in St. John’s [Newfoundland and Labrador]. In 2014, Atlantic Business Magazine would celebrate its 25th anniversary – no mean feat in the publishing business anywhere these days – and editor Dawn Chafe and I were trying to figure out an appropriate editorial way to mark that milestone. I’m not sure which of us came up with the idea to profile a series of key Atlantic Canadian business makers and economy shakers, but we quickly agreed John Risley had to be one of them.

Risley, after all, is a member in good standing in Canadian Business magazine’s Top 100 Wealthiest Canadians, the billionaire co-founder of Clearwater Seafoods Inc., “one of North America’s largest vertically integrated seafood companies and the largest holder of shellfish licences and quotas in Canada;” the driving force behind the evolution of Ocean Nutrition, the 16-year-old Nova Scotiabased company that had become the world’s largest producer of Omega-3 fatty acids by the time Risley sold it last year to Dutch-based Royal DSM for $540 million; and a major investor in Columbus Communications, a 10-year-old Barbados-based company providing cable TV‚ digital video, high speed internet access‚ digital telephones and corporate data services in 42 countries in the Caribbean, Central and South America.

These days, Risley lives with his wife Judy in a 32,000-square-foot Georgian-style mansion on a 300-acre sweet spot of ocean-fronted land near idyllic Chester, N.S., that once belonged to the founder of Sunoco, the American petrochemical giant. When he needs to go somewhere, or just get away from it all, he can hop aboard one of his small fleet of corporate aircraft or sail away in a luxurious 240-foot super-yacht “equipped with a helipad and a grand ‘country-house’- style interior.”

It’s not immediately apparent what these two individuals bring to a meeting on Canadian science policy but given the increasing insistence on the commercialization of science, perhaps they don’t really need to know anything about science but can simply share their business insights.

The first plenary session as you might expect from co-chairs whose interests seem to be primarily financial is titled: Procurement and Industrial Technological Benefits (ITB) and Value Propositions on the conference agenda webpage,

The Inside Story: Procurement, Value Propositions, and Industrial and Technological Benefits

Canada’s procurement policy and its associated value proposition and Industrial and Technological Benefit (ITB) policies have the potential to create powerful strategic opportunities for Canadian industry and R&D. These opportunities include increasing demand-side pull instead of the more common supply-side push. In addition, ITBs and value propositions can provide new opportunities for Canadian companies to enter and move up sophisticated global supply chains.

On the other hand, these policies might potentially further complicate an already complicated procurement process and mitigate the primary objective of equipping the Canadian Forces in a timely way. To achieve the significant potential economic development benefits, ITBs and value propositions must be designed and negotiated strategically. This will therefore require priority attention from the responsible departments of government.

An authoritative panel will bring a variety of perspectives to the policy issues. The panel will include members from: a Canadian company with a contract for naval vessel construction; a federal regional development program; a federal ministry responsible for the operation of the policies; a provincial government; and a retired military officer. The panel is chaired by Peter Nicholson who has had extensive experience in science and innovation policy, including its relationship with defense procurement.

An interesting way to kick off the conference: business and military procurement. Happily, there are some more ‘sciencish’ panels but the business theme threatens to dominate the 2014 conference in such a way as to preclude other sorts of conversations and to turn even the more classically ‘science’ panels to business discussions.

While my perspective may seem a little dour, David Bruggeman in his Sept. 26, 2014 posting on the Pasco Phronesis blog offers a more upbeat perspective.

Tweet the International Space Station on the solstice, June 21, 2014

On the heels of the nanosatellite project (see this June 19, 2014 posting) here’s an email announcement about a very interesting project for the Summer Solstice (June 21, 2014),

The June Solstice (Saturday, June 21) is the best time to view the International Space Station [ISS] in the northern hemisphere.

But now there¹s another way.

Crowdsource the pictures via Twitter.

Space enthusiasts are being encouraged to tag their tweets with #SpotTheStation and include a location name and it will go on an interactive map.

Astronaut Reid Wiseman had the idea while on the International Space Station.  His tweet for example was ³During #Exp40, spot the #ISS & tweet your town, country-or-state w/ #spotthestation (pics welcome); we’ll map it! bit.ly/SpotTheStation2²

Here’s a little more detail as to the company and agency behind this project,

Esri, a GIS mapping software provider, has partnered with the Center of Geographic Sciences in Canada to develop a Twitter app to pinpoint the exact location of the ISS sightings around the world in order to give a complete view. The global map documenting the recent ISS sightings is already live.

I have looked at the live map and tweeters have been active. You can check to see the locations. For example, as of June 19, 2014 1000 hours PDT, Canada has some 26 tweets while Florida has 40 and Munich tops them both with 132 tweets.

I have looked up the company, Esri, and found this on the About Esri History page,

Jack and Laura Dangermond founded Esri in 1969 as a small research group focused on land-use planning. The company’s early mission was to organize and analyze geographic information to help land planners and land resource managers make well-informed environmental decisions.

There’s a very interesting article on the Esri website, which provides some insight into the origins for the June 21, 2014 ‘#SpotTheStation’ project. Written by Carla Wheeler (an Esri writer), it is undated but there is mention of Chris Hadfield’s sojourn on the ISS and his attendance at an event in June 2013 after he landed. From Wheeler’s 2013 (?) article, A Map App Odyssey,

Today social media, with doses of humor, are very much a part of the space mission, with the National Aeronautics and Space Administration (NASA), the Canadian Space Agency (CSA), and many astronauts sending messages, videos, and photos back to Earth via Twitter, Facebook, and YouTube. Followers post messages for the astronauts too, making interaction about space interactive.

The photos Hadfield and fellow ISS astronaut Thomas Marshburn sent via Twitter inspired their follower David MacLean, a faculty member at the Centre of Geographic Sciences (COGS), Nova Scotia Community College, and his students to create a mapping app called Our World from the ISS. It used Esri ArcGIS Online to map more than 950 photographs of interesting places on Earth that Hadfield and Marshburn shot from space. They took the photos during their December 2012–May 2013 mission and posted the images on Twitter with their observations of each scene (in 140 characters or fewer, of course). Hadfield, a Canadian, was especially prolific and poetic. …

MacLean, also a Canadian, was intrigued by the astronauts’ unique perspective as they orbited 400 kilometers (250 miles) above earth, photographing everything from cities to barrier reefs and sand formations to smoke from brush fires. He didn’t want their geologically and geographically interesting images and descriptions—such as “taffy-twisted African rock” and the “yin and yang of ice and land”—to quickly get swallowed and lost in the fast-moving Twitterverse.

“[Hadfield] took pictures all over the earth, with wonderful prose as he described the outback of Australia and parts of Mauritania and Algeria that no one would [otherwise] get to see,” MacLean said. “Unfortunately, Twitter seems to be a very temporal medium, and all these wonderful pictures—these rich resources—slip away and you have to really look to find them.”

MacLean wondered if there was a way to preserve the images and messages in the Tweets in a form that was easy for people to find and view. He decided to try building a mapping app, which he and his students created using geographic information system (GIS) technology from Esri, online comma-separated value (CSV) files, and Google Docs spreadsheets in Google Drive. Their map displays icons, provided courtesy of the Canadian Space Agency, that look like small space stations. These show the approximate (or, at times, quite accurate) locations of each photograph. Viewers can pan the map, zoom in to any area of interest, and tap an icon. A pop-up window will appear that includes a thumbnail of the picture and the message from the astronaut. You can also click the thumbnail to see the full-size Tweet in the astronauts’ Twitter feed. (Clicking the photo in Twitter will then bring up a larger, sharper image.) It’s a little like seeing photos of landscapes in National Geographic—only taken from space.

Tap an icon north of Medina, Saudi Arabia, to see Hadfield’s May 3 [2013?] photo of the Harrat Khaybar volcanic lava field and read his post: “The Earth bubbled and spat, like boiling porridge, long ago in Saudi Arabia.” Another geologic wonder caught his eye Down Under: “A splash of dry salt, white on seared red, in Australia’s agonizingly beautiful Outback.”

So, on June 21, 2014 get ready to tweet ‘#SpotTheStation’ and have a joyous Summer Solstice!

Atlantic Canada’s Lamda Guard signs deal to test nanocomposite windshield film with Airbus

This story comes from Nova Scotia although you wouldn’t know it if you’d only read the June 5, 2014 news item on Azonano,

Lamda Guard, a company based in Atlantic Canada, has signed an agreement with leading aircraft manufacturer Airbus to test a breakthrough innovation designed to deflect unwanted bright light or laser sources from impacting jetliner flight paths, and causing pilot disorientation or injury.

A June 4, 2014 news release (either from Lamda Guard.com or MTI [metamaterial.com]; Note: More about the multiple webspaces later] and there’s a PDF version here), which originated the news item, provides a little more information about the technology and the perspectives from various stakeholders

Lamda Guard’s innovative thin films utilize metamaterial technology on cockpit windscreens to selectively block and control light coming from any angle even at the highest power levels. “Today marks a milestone in optical applications of nano-composites,” said George Palikaras, President and CEO of Lamda Guard. “Through our collaboration with Airbus we are working to introduce our metamaterial technology, for the first time, as a solution to laser interference in the aviation industry.” The announcement today comes within weeks of the release of an FBI [US Federal Bureau of Investigation] report citing 3,960 aircraft laser strikes in the US in 2013 according to the Federal Aviation Authority (FAA).

Senior Vice President of Innovation Yann Barbaux stated: “At Airbus, we are always on the lookout for new ideas coming from innovative SMEs [small to medium enterprises], such as Lamda Guard. We are very pleased to explore together the potential application of this solution to our aircraft, for the benefit of our customers.”

Over the past year Lamda Guard has been working with the research community at the University of Moncton and the University of New Brunswick, as well as stakeholders, investors and funders to highlight the benefits of nano-composites. The Atlantic Canada Opportunities Agency (ACOA) in particular has played an important role in Lamda Guard’s research and development efforts. In 2012, ACOA assisted Lamda Guard with technology commercialization and recently upgraded its contribution to $500,000 to further assist the company in developing and manufacturing its products for the aviation industry.

The Lamda Guard Airbus partnership marks the first time an optical metamaterial nano-composite has been applied on a large-scale surface.

I tried to find more information about the technology and tracked down this tiny bit, from the What are MetaMaterials? webpage on the MTI website,

A metamaterial typically consists of a multitude of structured unit cells that are comprised of multiple individual elements, which are referred to as meta-atoms. The individual elements are assembled from conventional microscopic materials such as metals and/or plastics, which are arranged in periodic patterns.

MTI’s precisely designed structures are developed with proprietary algorithms, producing a new generation of optical products that are built in state-of-the-art thin film nano-fabrication labs. MTI’s proprietary software accurately predicts the desired design pattern to generate a unique material that meets customer specifications. MTI’s sleek designs mean manufacturers can reduce their cost of materials significantly while increasing performance, e.g. by increasing the light output of an LED bulb or increasing the absorption of light in a solar panel.

Multiple webspaces and presences

While Lamda Guard has a .com presence, you will find yourself on the metamaterial.com website in the Lamda Guard webspace (I suppose you could also call it a subsite) once you start clicking for more information.  In fact, MTI owns three Lamda companies as per this description from the Our Company webpage on the MTI (metamaterial.com) website (Note: Links have been removed),

MTI is an advanced materials and systems engineering company developing and commercializing innovative optical solutions. The company’s core team has over 200 years of combined experience at the forefront of the design and implementation of metamaterials, making MTI a pioneer in bridging the gap between the theoretical and the possible.

MTI specializes in metamaterials, nanotechnology, theoretical and computational electromagnetics. The company’s in-house expertise enables the rapid development of a wide array of metamaterial applications, covering a diverse range of markets.

MTI’s technologies are adaptable and can be custom-designed to suit an industry manufacturer’s specifications allowing for scalability and rapid prototyping with minimum overheads. MTI provides access to world class nano-composite research and development, including specialty, as well as customized, products and licensing of its proprietary solutions to customers ranging from government to private companies.

MTI has three wholly owned subsidiaries:

Lamda Guard Inc. which develops advanced filters to block out selected parts of the light spectrum, protecting the eyes from lasers or other sources of hazardous light.

Lamda Solar Inc. products increase the efficiency of solar panel cells by absorbing more light.

Lamda Lux Inc. technology increases the delivered lumens and reduces the cost of thermal management of LED lighting.

Interestingly, the Lamda Guard Management team‘s (in the Lamda Guard webspace) Chief Science Officer, Dr. Themos Kallos, and Chief Intellectual Property Officer, Dr. Quinton Fivelman, both appear to reside in the UK (assuming I looked at the correct LinkedIn profiles).  Coincidentally, MTI’s contact page lists the company’s headquarters as being in Nova Scotia but Sales, Research and Development would seem to be located in the UK.

Presumably, this company is maximizing its access to government grants and tax incentives in both the UK and Canada. The deal with the Airbus suggests that this has been a successful strategy possibly leading to commercialized technology and, hopefully, jobs.

Governing in the Dark; a March 5, 2014 national (Canada) lecture

I think it’s pretty easy to guess the perspective from the title of the lecture, Governing in the Dark: Evidence, Accountability and the Future of Canadian Science (the third in a series titled, The Lives of Evidence) being offered by the Situating Science project on March 5,2014. Here’s more about it from the event page,

The national Situating Science project and partners are pleased to present the third talk in the national lecture series:

The Lives of Evidence
A multi-part national lecture series examining the cultural, ethical, political, and scientific role of evidence in our world.

Part 3:
Governing in the Dark: Evidence, Accountability and the Future of Canadian Science

Scientists are becoming increasingly concerned about the Canadian government’s attitude towards science. They are concerned about declining federal investment in public interest science; a shift away from federal funding of basic research to business-oriented research; policies that restrict the communication of scientific information among government scientists and to the public; and – despite assurances to the contrary from federal ministers – an increasingly cavalier attitude towards science-informed decision-making. Are these symptoms of an ongoing erosion of basic democratic principles? What are some possible therapeutic and preventative interventions?
